We've only been playing for a few weeks now and already there are a number of spots that are proving valuable for farming certain items in the game. The one I am going to show you today is right in the humans starting zone just to the south-west of the Western Divinity Dam. Getting the blood vials and venom sacks from this area are actually part of an event so you can't just go there and repeat the quest over and over again. The thing you can do though is go there and help people farm the quest and get the rewards for yourself. The mobs that you are going to be farming are called Orchard spiders. They have younger mobs with them called Orchard hatchlings as well.
At the end of the event there is usually a dynamic event which begins as well. The goal of this is to take down what is essentially a boss spider. It is much bigger than all of the other Orchard spiders in the zone and takes a few more people. When you kill it this is where you can get the Tiny Venom Sacs as well. Between the blood vials and the venom sacs this orchard is a pretty good spot to go to if you need a few of either of these two items quickly.
While I was doing this quest and since I've finished it and gone back to farm for blood vials I usually spend about 10 to 15 min. there and I can walk away with anywhere between three and five blood vials. I don't know if there are any better spots than this at the moment – at least I have not found any personally. This is one of the very early zones of the game and it's actually the humans starting zone. It doesn't really make much difference because Guild Wars 2 is set up to depreciate your abilities to the current zone that year-end. So it doesn't matter if you are level 80 and going back to the human starting zone it's actually going to decrease your abilities down to what they would be if you are leveling this zone for the first time.
The region that it is in is known as Kryta – it is located just to the southwest of Divinities Reach. It also has a waypoint there as well so you can travel to it quickly. This is just one of the many different farming spots I found since I started playing Guild Wars 2. If you found a better spot for farming blood vials please feel free to comment on this article. I know that there are perhaps thousands of different spots to farm for any given item, but I am just one person and I can't possibly find them all.
Where do you farm for Weak Blood Vials?
Last thing before I go. I was just cruising through YouTube and found a video that a user made which actually shows the Orchard spider event. Here is the video for you guys. The player who recorded this video showed up part ways through the event so we didn't get to do as much farming as one would expect, but you do get to see that he picks up a few venom sacs at the end so it really becomes all worth it.
